SPECIFICATION forming part of Letters Patent No. 340,661, dated April 27, 1886.

Application filed December 39, 1885. Serial No 187,009. (No model.

To all whom it may concern.-

Be it known that I, GEORGE P. CRAGIN, a citizen of the United States, residing at Fergus Falls, in the county of Otter Tail, State of Minnesota, have invented certain new and useful Improvements in Nut-Locking Bars, of which the following isaspecification, reference being had therein to the accompanying drawlugs.

My invention relates to a nut-locking bar;

and it consists in the construction and arrangement of the same, which will be more fully hereinafter described, and definitely pointed out in the claim.

The object of my invention is to provide a nut-locking bar for securing a nut in such a position that it cannot turn or become displaced from its bolt, said bar being simple in its construction, strong and durable, and easily secured in its desired position. I attain these objects by the device illustrated in the accompanying drawings, wherein like letters of ref erence indicate similar parts in the several views, and in which- Figure 1 is a perspective view of a portion of a rail illustrating thejoint thereof with the angle-plate secured in position and with my improved nut-locking bar applied under the nuts. Fig. 2 is a perspective view of my improved nut-locking bar detached. Fig. 3 is a view similar to Fig. l, but with the lockingbar applied in connection with an ordinary fish-plate.

A indicates a portion of a rail showing a joint with the angle-plate B set in position over the joint.

0 represents the nuts of the sccuringbolts, which pass through the rail A, angle-bar B, and under which my improved locking-bar D 40 is placed, said locking-bar being secured to the sleepers E by suitable means. The lockingbar D is formed of metal, and. has two end seats, (Z, which rest on the angleplate B, and conform to the contour thereof. The said seats (Z are provided with apertures d in their lowermost part, through which spikes may be driven into the sleepers E. The end seats, (1, are connected by metal web d", cast integral therewith, said web being of less transverse breadth and vertical thickness than the end 0 seats, and in consequence of such formation leaves a recess between the said seats, allowing them to extend outwardly beyond the web at". The underside of this web 01 does not rest upon the angle-plate B. but has cast therewith 5 a series of projections, (25, which form seats for this portion of the locking-bar,which rest on the angle-plate. Bet-ween each of these projections (Z an arch, dfiis formed, by which means greater strength with a less amount of metal is obtained.

In Fig. 3 I have illustrated the locking-bar D,applied in connection with an ordinary fishplate. In this instance the rest (Z is situated in the central portion of the bar, the web d extending at about right angles from either side thereof. The projections d are constructed on each end of this bar, and two arches, (1, one on each side of the central seat,

(2, are shown, Only one spike is required to secure this form of locking-bar D, which is driven through. the recess (1, formed in the central seat, (1.

To apply my improved nut-locking bar the operation is as follows: The angle-plate B or 7 fish-plate having been secured overthe joint in the rail A, and the nuts G,with their lower faces on a true line,screwed home, the lockingbar D is placed under the lower faces of the nuts 0, and secured to the sleepers E by spikes 8o driven through the recesses (1, formed in the seats (1. When the lockingbar is in its posi tion, the end or central seats will rest firmly on the angle-plate or rail and against the vertical portion of the angle-plate or fish-plate. This locking-bar is light and simple in its construction, dispensing with the use of a large quantity of metal, and thus avoiding the cast ing of a cumbersome and heavy bar. By the formation of arches between the projections 0 formed integral with the central web the bar is strengthened and rendered durable. A further advantage of this bar is that it conforms to the contour and arrangement of any angleplate or fish-plate, thus avoiding the necessity 5 of constructing it to fit the plate to which it is desired to apply it.

It is obvious that any form of nut can be i recesses formed therein, a central web cast integral with the end seats of less transverse breadth and vertical thickness than said seats, and projections forming seats for said web, having arches formed between thennwhereby the bar is rendered lightin construction, strongand durable, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

GEORGE P. ORAGIN.
